In Resident Evil 2 (2019), combine the Battery from the S.T.A.R.S. Office with the Electronic Gadget from the Operations Room to make a Detonator. Use it on the C4 barricade in the 3F West Storage Room to reach the Maiden Statue and its medallion.

Where to find the Battery and Electronic Gadget

  • Electronic Gadget: Operations Room, Police Station 1F. It needs a Battery to function as a Detonator. Item reference
  • Battery: S.T.A.R.S. Office, Police Station 2F. The item reference describes it as a standard 9-volt battery. Item reference

How to use the Battery

  1. Collect the Electronic Gadget in the Operations Room on 1F.
  2. Collect the Battery in the S.T.A.R.S. Office on 2F.
  3. Open your inventory and combine the Battery with the Electronic Gadget. The result is the Detonator.
  4. Go to the C4 barricade in the West Storage Room on 3F and use the Detonator. The blast opens access to the Maiden Statue. Walkthrough

Get the Maiden Medallion

Once the barricade is cleared, interact with the Maiden Statue and enter the symbol sequence for your scenario. PowerPyx lists different sequences for the main scenario and the B scenario:

Scenario Maiden Statue sequence
Main scenario Woman, Bow, Snake
B scenario Ram, Harp, Bird

These sequences are listed by PowerPyx’s walkthrough; use the row matching your scenario rather than treating one sequence as universal.

Is the Battery used for anything else?

The Battery is an in-game key item, not a request to find or buy a real-world 9V battery. The documented use is to combine it with the Electronic Gadget and create the Detonator; no other use is established by the cited item references.
